21% of the students at a High are in Maths group, 15 % are in science group, and 6 % are in both. If a student is selected rando

mihalych1998 [28]

Answer:

Step-by-step explanation:

The probability of picking a maths student = 21% = 21/100

The probability of picking a science student = 15% = 15/100 = 3/20

The probability of picking in both = 6/100 = 3/50

The probability that the student is in maths or science = 21/100 - 15/100 = 6/100 = 6%.

Quadrilateral BCDE is a rhombus. What is DE?<br> D<br> с<br> 9z<br> E<br> 2+72<br> B

aleksklad [387]

Answer:

DE = 81

Step-by-step explanation:

The sides of a rhombus are congruent , thus

9z = z + 72 ( subtract z from both sides )

8z = 72 ( divide both sides by 8 )

z = 9

Then

BC = 9z = 9 × 9 = 81

Since the sides are congruent, then DE = 81

Lucy is a dress maker. She sews \dfrac47

Strike441 [17]

Answer:

$\frac{16}{21}$ dresses

Step-by-step explanation:

We are given that

Lucy sews dress in 3/4 hours= $\frac{4}{7}$ of dress

Lucy sews at constant rate.

We have to find the number of dresses sewed by Lucy in hour.

To find number of dress sewed by Lucy in 1 hour we will use unitary method.

By using unitary method

Lucy sews in 3/4 hours= $\frac{4}{7}$ dress

Lucy sews in 1 hour= $\frac{\frac{4}{7}}{\frac{3}{4}}$

Lucy sews in 1 hour= $\frac{4}{7}\times \frac{4}{3}$

Lucy sews in 1 hour= $\frac{16}{21}$ dresses

Hence, Lucy sews $\frac{16}{21}$ dresses in 1 hour.
